Brenner tumors of the ovary: A case series in a teaching institute center.

Brenner tumors of the ovary are very rare, and mostly benign. Borderline Brenner tumors are rare and malignant Brenner tumors are even much rarer with a worse prognosis. This study was carried out in the Department of Pathology, VSSIMSAR, Burla, Odisha over a period of 3 years. A histopathology study was done in all the cases, while immunostaining was done in selected cases only. A total of seven cases were studied, out of which four (57.14%) cases were diagnosed as benign Brenner tumors, two (28.57%) cases as borderline Brenner tumors, and one (14.28%) case as malignant. Histopathology study is the gold standard for diagnosis of Brenner tumor, with the aid of immunostain whenever necessary.
